In this process, the size or shape of the components shown in the drawings may be exaggerated for clarity and convenience of description. In addition, terms that are specifically defined in consideration of the configuration and operation of the present invention may vary depending on the intention or custom of the user or operator. Definitions of these terms should be made based on the contents throughout the specification. And the spirit of the present invention is not limited to the embodiments presented, those skilled in the art of understanding the spirit of the present invention can easily implement other embodiments within the scope of the same idea, but also within the scope of the present invention Of course.
본 발명의 실시예에 따른 가이드프레임 지지장치(10)는 도 2에 도시된 바와 같이, 힌지바(100), 지지바(200), 힌지링크(300), 비틀림스프링(400), 이격거리조절장치(500),스토퍼볼트(600) 및 결합부재(700)를 포함한다.Guide frame support device 10 according to an embodiment of the present invention, as shown in Figure 2, the hinge bar 100, the support bar 200, the hinge link 300, the torsion spring 400, the separation distance control Apparatus 500, stopper bolt 600 and coupling member 700.
상기 힌지바(100)는 상기 가이드프레임(G)의 내주면에 결합된다.The hinge bar 100 is coupled to the inner peripheral surface of the guide frame (G).
상기 지지바(200)는 상기 힌지바(100)를 중심으로 소정 각도로 회동한다.The support bar 200 rotates at a predetermined angle about the hinge bar 100.
상기 힌지링크(300)는 상기 힌지바(100)의 양단에 그 일측이 힌지 결합되고, 상기 지지바(200)의 양단에 그 타측이 연결된다.One side of the hinge link 300 is hinged to both ends of the hinge bar 100, the other side is connected to both ends of the support bar (200).
상기 비틀림스프링(400)은 상기 한쌍의 지지바(200) 사이에 마련되고, 상기 지지바(200)가 상기 힌지바(100)를 중심으로 소정 각도로 회동하도록 탄성력을 제공한다.The torsion spring 400 is provided between the pair of support bars 200, and provides the elastic force to rotate the support bar 200 at a predetermined angle about the hinge bar 100.
상기 이격거리조절장치(500)는 상기 힌지바(100)에 마련되어 상기 힌지바(100)를 중심으로 회전하는 캠플레이트(510) 및 상기 캠플레이트(510)를 가압 고정하는 고정부재(520)를 포함하고, 상기 배관과 상기 가이드프레임(G) 간 이격거리를 조절한다.The separation distance adjusting device 500 is provided on the hinge bar 100 to the cam plate 510 rotating around the hinge bar 100 and the fixing member 520 for pressing and fixing the cam plate 510. It includes, and adjusts the separation distance between the pipe and the guide frame (G).
즉, 상기 고정부재(520)를 풀면 상기 캠플레이트(510)는 회전이 가능하므로, 상기 캠플레이트(510)를 적당히 회전시켜 이격거리를 조절한 후 상기 고정부재(520)를 조이면 상기 캠플레이트(510)는 회전하지 않게 고정되어 이격거리가 조절된다.That is, since the cam plate 510 is rotatable when the fixing member 520 is released, the cam plate 510 is appropriately rotated to adjust the separation distance, and then the cam plate 510 is tightened. 510 is fixed so as not to rotate, the separation distance is adjusted.
이때, 상기 고정부재(520)는 통상 나사볼트가 사용된다.At this time, the fixing member 520 is usually used a screw bolt.
상기 스토퍼볼트(600)는 상기 힌지링크(300)를 관통하며 일측이 상기 가이드프레임(G)을 가압하여 상기 비틀림스프링(400)이 제공하는 탄성력을 조절한다.The stopper bolt 600 penetrates the hinge link 300 and one side presses the guide frame G to adjust an elastic force provided by the torsion spring 400.
상기 결합부재(700)는 상기 힌지바(100)를 관통하여 마련된 관통홈에 안착되는 결합볼트가 상기 가이드프레임(G)에 고정되어, 상기 가이드프레임 지지장치(10) 전체가 상기 가이드프레임(G)에 고정된다.The coupling member 700 is a coupling bolt seated in the through groove provided through the hinge bar 100 is fixed to the guide frame (G), the entire guide frame support device 10 is the guide frame (G) It is fixed to).
상기 가이드프레임 지지장치(10)의 탄성력 조절방법은 도3, 도 4, 및 도 5에 도시된 바와 같다.How to adjust the elastic force of the guide frame support device 10 is as shown in Figures 3, 4, and 5.
도 3에서 도시된 상기 가이드프레임 지지장치의 탄성력을 기준하여 설명한다.It will be described with reference to the elastic force of the guide frame support device shown in FIG.
먼저, 도 4에 도시된 바와 같이, 상기 스토퍼볼트(600)를 조이게 되면 도 3에 비해 한쌍의 상기 힌지링크(300)가 이루는 각도가 커지게 되고, 상기 비틀림스프링(400)의 탄성력이 증가한다.First, as shown in FIG. 4, when the stopper bolt 600 is tightened, an angle formed by the pair of hinge links 300 becomes larger than in FIG. 3, and the elastic force of the torsion spring 400 is increased. .
한편, 도 5에 도시된 바와 같이, 상기 스토퍼볼트(600)를 풀게 되면 도 3에 비해 한쌍의 상기 힌지링크(300)가 이루는 각도가 작아지게 되고, 상기 비틀림스프링(400)의 탄성력이 감소한다.On the other hand, as shown in FIG. 5, when the stopper bolt 600 is loosened, the angle formed by the pair of hinge links 300 becomes smaller than in FIG. 3, and the elastic force of the torsion spring 400 is reduced. .
이때, 도 4의 경우 도 3에 비해 상기 가이드프레임(G)과 상기 배관의 이격거리가 다소 짧아지고, 도 5의 경우 도 3에 비해 상기 가이드프레임(G)과 상기 배관의 이격거리가 다소 길어지는 것을 알 수 있다. 따라서 탄성력의 조절시 이격거리가 다소 변동되지만 이는 상기 이격거리조절장치(500)로 보정이 가능하다.In this case, the distance between the guide frame G and the pipe is slightly shorter than that of FIG. 3 in FIG. 4, and the distance between the guide frame G and the pipe is slightly longer than FIG. 3. You can see the loss. Therefore, the separation distance is slightly changed when the elastic force is adjusted, which can be corrected by the separation distance adjusting device 500.
한편, 도 3 내지 도 6에 도시된 바와 같이, 캠플레이트(510)는 그 회전중심에서 말단까지의 거리가 다른 다각형으로 구성될 수도 있다. 이러한 경우, 상기 캠플레이트(510)는 그 회전중심에서 서로 다른 거리의 말단으로 인해 상기 스토퍼볼트(600) 또는 상기 이격거리조절장치(500)를 사용하지 않아도 이격거리의 조절이 가능하다.On the other hand, as shown in Figures 3 to 6, the cam plate 510 may be composed of a polygon with a different distance from the center of rotation to the end. In this case, the cam plate 510 can be adjusted without the use of the stopper bolt 600 or the separation distance adjusting device 500 due to the end of the different distance from the center of rotation.
도 3 및 도 6을 비교하면 상기 가이드프레임(G)과 접촉하는 4각형의 상기 캠플레이트(510)의 말단이 각각 다른 경우 이격거리가 달라짐을 알 수 있다. Comparing FIGS. 3 and 6, when the ends of the cam plate 510 of the quadrilateral contacting the guide frame G are different, it can be seen that the separation distance is different.
한편 도 3 내지 도 6에서는 4각형의 캠플레이트(510)만 도시되었으나, 6각형, 기타 3각형 이상의 다각형을 이루며 그 회전중심에서 말단까지의 거리가 다른 말단을 가지는 캠플레이트가 사용될 수 있고, 다각형의 말단의 수에 따른 다양한 단계의 이격거리의 조절이 가능하다. 즉, 제1실시예로써 캠플레이트(510)가 4각형인 경우 4단계의 이격거리 조절이 가능하다. 또한, 제2실시예로써 캠플레이트(510)가 6각형인 경우 6단계의 이격거리 조절이 가능하다.Meanwhile, in FIGS. 3 to 6, only the cam plate 510 of the quadrangular shape is illustrated, but a cam plate having a hexagonal shape, a polygonal shape or other triangular shape or more, and having a distal end distance from the center of rotation may be used. It is possible to adjust the separation distance of various stages according to the number of ends of. That is, when the cam plate 510 is a quadrangular shape as the first embodiment, the separation distance can be adjusted in four steps. In addition, as a second embodiment, when the cam plate 510 is hexagonal, the separation distance of six steps may be adjusted.
